Extruder fault diagnosis and maintenance

I. Overview
Plastic products are produced by plastic machinery and equipment such as extruders. The machinery and equipment are the material and technical basis that a factory produces. It is one of the important factors that determines the economic efficiency of an enterprise. Whether the production can be normal depends to a large extent on the perfection of the production equipment. To allow enterprises to obtain better economic returns, including equipment status is good or bad, the level of equipment maintenance costs, but also a great impact on the assessment project. The quality of the equipment plays an important role in the consumption of raw materials, power consumption, quality and quantity of the products, and reduction of the manufacturing cost of the products. Therefore, in a manufacturing enterprise, whether it be the enterprise’s leaders or workers, it should recognize the importance of strengthening the management of equipment and attaching importance to the maintenance and repair of equipment. ⑪, equipment management content An enterprise from the day the plant was established equipment power management department, a full-time technical staff on the plant’s equipment management. One of the equipment maintenance and repair, only one of the equipment management. This includes the selection of equipment specifications, ordering, transportation, acceptance into the plant, installation, commissioning, operation, maintenance, repair and stop production and storage. To be fully managed. Equipment specifications model selection, which is based on the size of the investment in the enterprise and the planned investment returns shall prevail to design and calculate the specifications of the extruder model and select the appropriate equipment name, model specifications and so on. Therefore, the equipment management technician should be a professional technical management personnel who has the knowledge of production technology, mastering the structure of machinery and equipment and how to manage the equipment. The factory should unify the development of a more complete system of equipment management: equipment management practices, equipment maintenance responsibility system, equipment operating procedures, equipment maintenance responsibility system, equipment relocation, storage and scrap application procedures. ⑫, the correct and reasonable use of equipment and equipment The working life of the equipment, the level of production efficiency and product quality is good or bad and equipment manufacturing quality and specifications related to the choice of model. However, how to make the operators use the equipment reasonably and pay attention to the maintenance, which has a direct relationship with the extension of the service life of the extruder equipment and the production efficiency that the equipment should normally have. ① extruder production line corresponding ancillary equipment, each machine’s production capacity to match. Coordination of all equipment. Up and down the production process for more than the amount of demand and the amount greater than the supply, there is a stop waiting to choose not complete. ② According to product specifications to choose the production of extruder specifications

With a large format extruder to produce smaller sizes, increasing power consumption, expediting extruder wear, and increasing the cost of the product, it is an extremely uneconomical option. ③ Let the equipment work in the best condition. It should be equipped with appropriate skilled operators. Workers are required to have skilled operating techniques and to understand the performance, structure, and specification range of processed products. At the same time, also know how to maintain the equipment he used. For new workers must be technically trained to understand the performance of the equipment, structure, memorize the operating procedures and how to maintain the equipment. And the actual operation of the training. These content to pass the examination before induction work. ④ equipment work place to have a good environment. This is also a condition to extend the service life of the equipment. In the workshop, equipment should be moisture-proof, anti-corrosion, anti-pressure and sandstorm prevention. Let it work in a clean, non-polluting environment. ⑬, the relationship between equipment maintenance and repair Equipment maintenance and repair, is the equipment of two different methods of maintenance. But the purpose is one, I hope production equipment in the best operating conditions, to ensure that equipment has the highest yield and the best products, to the greatest extent possible to extend the working hours of equipment. Equipment maintenance is a regular work, including: Require the operating staff strictly in accordance with the operating procedures of the machine using the equipment, operating the production, regular cleaning, scrubbing equipment dust and oil and lube oil work, inspection, Observe the operation of the machine and find out the problem promptly remove the relevant personnel. This can delay wear and tear on machine parts and increase the life of the machine. Equipment repair is to repair the machine parts due to normal or abnormal causes of damage. Through the repair and replacement, the equipment to restore normal working ability, this is the purpose of repair. It should be noted that maintenance and repair are equally important tasks. Maintenance is a protective measure against wear and tear on equipment parts. Repairing and replacing parts is an essential means to ensure the normal operation of the equipment and make the equipment perform its original functions. These two tasks should be well integrated to prevent accidents and take preventive measures. In the machine parts damaged can not work before the timely repair replacement, so as to ensure that the machine has a good working condition.
